Jake Smolinski (shoulder) will begin a minor league rehab assignment with High-A Stockton on Saturday.

It's Smolinski's first game action since undergoing shoulder surgery in spring training. He'll serve as the DH on Saturday. Depending on how he progresses in his throwing program, Smolinksi could be an option for the Athletics' outfield sometime next month.

Athletics acquired OF Dustin Fowler, INF/OF Jorge Mateo, and RHP James Kaprielian from the Yankees for RHP Sonny Gray and $1.5 million in international spending money.

Fowler ruptured the patella tendon in his right knee in June when he crashed full-speed into the outfield wall in the first inning of his MLB debut and he will miss the remainder of the 2017 season, but the talented 22-year-old should be ready to rock next spring. He was batting .293/.329/.542 with 13 home runs and 13 stolen bases through 70 games this season with Triple-A Scranton/Wilkes-Barre.

Andrew Triggs had season-ending surgery on Thursday to repair a torn labrum in his left hip.

Triggs tried rehabbing the injury for over a month, but it obviously didn't work so he decided to go under the knife. The right-hander is expected to be ready to throw off a mound in time for spring training next year. Triggs got off to a great start in 2017 but rocked in his last two outings before going on the DL, ultimately finishing with a 4.27 ERA over 12 starts.

Wahl made the decision to have the operation after visit with specialist Dr. Gregory Pearl in Dallas. He has been sidelined since late May with shoulder issues and is now officially done for the season.
